Drive coupling assembly (50) for a high-speed rotating brush, comprising:
- a coupling head (100) having a coupling head rotation axis (L ch ) and including three drive surfaces (106) which are arranged to be rotationally symmetrical through 120° with respect to said coupling head rotation axis; and
- a coupling member (200), having a coupling member rotation axis (L cm ) and including three first drive surfaces (210a) which are arranged to be rotationally symmetrical through 120° with respect to said coupling member rotation axis,
wherein said coupling head (100) and said coupling member (200) are detachably couplable, such that, in a coupled condition, their rotational axes ( L ch , L cm ) are aligned and the coupling head is rotatable to drive each of its drive surfaces (106) in contact with a respective first drive surface (210a) of the coupling member, to thereby exert both a torque and an axially directed force on the coupling member. |
